Required CredentialsHigh school diploma or equivalent; some roles may require certificationAssociate degree or relevant certification in laboratory sciences
Work EnvironmentEducational, research, or clinical labs; supervised settingClinical, research, or industrial labs; more independent tasks
Employer & Industry UsageEducational institutions, research centers, hospitalsHospitals, biotech firms, pharmaceutical companies
Common Search & ComparisonEntry-level, support roles in labsTechnical, more specialized lab work

The main difference between a Junior Lab Assistant and a Laboratory Technician lies in their qualifications and responsibilities. Junior Lab Assistants typically have a high school diploma and perform basic support tasks under supervision, while Laboratory Technicians usually hold an associate degree and handle more technical, independent duties. Both roles are essential in laboratory settings, but Laboratory Technicians often require more specialized training and experience.

How much does a junior lab assistant get paid?

A junior lab assistant typically earns between $12 and $20 per hour, depending on the location, industry, and level of experience. Entry-level positions may start at the lower end of this range, with pay increasing as skills and responsibilities grow.

Can you get a junior lab assistant job with no experience?

Junior lab assistant positions often require some basic knowledge of laboratory procedures and safety protocols, but many entry-level roles are open to candidates with little or no prior experience. Employers may provide on-the-job training and look for qualities such as attention to detail, willingness to learn, and basic technical skills. Certifications or coursework in science or laboratory techniques can improve chances but are not always mandatory for entry-level roles.

What challenges might a junior lab assistant face when learning to maintain laboratory equipment?

As a Junior Lab Assistant, you may encounter challenges in understanding the proper handling and calibration of complex laboratory equipment, especially when you are new to the environment. Each instrument may have specific maintenance protocols, and mistakes can impact research outcomes. However, most labs provide hands-on training and mentorship from senior staff, so being proactive in asking questions and carefully following standard operating procedures can help you quickly build confidence and competency.

What skills and qualifications are needed to be a junior lab assistant?

To thrive as a Junior Lab Assistant, you need a basic understanding of laboratory techniques, safety protocols, and often a high school diploma or associate degree in a science-related field. Familiarity with lab equipment, data entry systems, and basic software like Microsoft Excel is typically required. Attention to detail, strong organizational skills, and the ability to follow instructions precisely are valuable soft skills. These competencies ensure the accuracy and safety of lab procedures, supporting reliable research and daily operations.

Job description

Department Overview

The Department of Pediatrics is looking for a Research Assistant (1.0 FTE) to join our research team with experience in a neuroscience lab. 

The applicant should have a degree in Life Sciences relevant experience including familiarity with basic Molecular Biology techniques (PCR, RT-PCR) and/or basic Microscopy.

The applicant should be comfortable handling rodents (neonatal and adult).

Function/Duties of Position

This position is ideal for a candidate seeking to gain more experience relevant to human physiology, because the project involves work not only with a neonatal rodent model of brain hypoxia, but also with a large animal model of fetal brain hypoxia in pregnant sheep. These projects will provide excellent experience to launch a career in biomedical sciences as a physician scientist, a biomedical researcher or as preparation for medical school. The projects require a mature individual with excellent time management skills who will work primarily on projects involving live newborn mice and also intermittently assisting in an active sheep laboratory.  Both projects are focused on complementary questions related to the impact of exposure to hypoxia on brain development. Both of these NIH-funded research projects will define mechanisms leading to disruption of neuronal development and disturbances in long-term learning and memory mechanisms.  The candidate will work with our chief sheep surgeon and must be comfortable with handling animals (mice and sheep) and providing surgical support in a large animal surgery suite with a sterile operating room. Prior small or large animal handling experience is required. Additional training will be provided by faculty working in the sheep and rodent labs.

The projects will employ a range of approaches ranging from histology to advanced molecular approaches.  These include analysis of neuronal morphology using advanced microscopic approaches for single cell reconstruction, electrophysiology, advanced MRI analysis and behavioral studies.  Some studies are on-going under the supervision of postdoctoral fellows or junior faculty in the lab. The candidate will work closely with these senior individuals on independent aspects of the rodent and sheep hypoxia studies. The successful candidate will also have the opportunity to learn a range of techniques that we routinely use including animal surgery, tissue sectioning/staining for quantitative analysis, western blotting and other molecular techniques. Responsibilities include designing and conducting experiments, data analysis, record-keeping and data presentation.  Attend weekly lab meetings and present your research. 

Relevant publication illustrating the nature of the projects include: Sheep studies: Science Translational Medicine 16,5(168):168ra7, 2013; Journal of Neuroscience, 39(40):7853-7871, 2019, Annals of Neurology 70: 493-507, 2011. Mouse studies: Journal of Neuroscience 46(16): e1643252026.

Required Qualifications
  • Bachelor's degree in Life Sciences or OR Associate's AND 3 years of relevant experience OR4 years of relevant experience OR Equivalent combination of training and experience.
  • The applicant should be comfortable handling rodents (neonatal and adult).
  • The applicant should have familiarity with basic Molecular Biology techniques (PCR, RT-PCR) and/or basic Microscopy.
  • Computer knowledge/skills.
  • Good communication skills.
  • Excellent recordkeeping
  • Possess the ability to work independently while functioning within a team environment.
Preferred Qualifications
  • Coursework taken pertaining to Neurobiology/Neuroscience or Physiology is preferred.
  • Familiarity with any one or all of the following:
    • confocal/fluorescence microscopy
    • cell culture techniques handling fixed/frozen tissue sections for immunohistochemistry
    • mouse genetics
    • protein assays
  • Experience in advanced molecular biology, biochemistry techniques.
  • Excellent organizational and communication skills, be enthusiastic about their work, and be highly motivated to succeed in a multi-disciplinary/multi-collaborator setting that provides a wealth of opportunities in one of the major universities for neuroscience research in the U.S.
